I installed and the sound was great!!!It’s a very very quiet amplifier with a grand sound!!! It’s the first time that I construct an amp with SMD components and I was inquisitive how the sound was.Although the amp is very new, only few hours is working, and I am sure that after some working hours burning of all components the sound will be more better from excellent!!!Well done for your modules!!!Tasos, Greece

HelloThis is my story of how I went when I wanted to build the ultimate bass amp.Here is the story of “Tower of Power” as they were baptized rather quickly when the project was revealed among the local DIY community.First of all I wanted two dedicated mono subwoofer amps that bettered the Crown K2s they were to replace.After having read and heard a lot of positive stuff about these Aussie Amps, I felt they fulfilled my pre defined criteria very well.Class AB, high power, high damping factor with many output devices and what seemed to be good quality parts.Second I wanted an unusual design, that also limited the floorspace needed, since my livingroom was already crowded by horns and and electronics.After a lot of research I landed on building a pair of Holton 800s, but in a vertical arrangement instead of the classic rack style cabinetBy coincidence I came across...

Having upgraded my speakers I was looking for something a little better then my monobloc chip-amps, but wanted to keep the chassis as there a good fit with the rest of my system.So using 45V rails and 20,000uf per unit, in went the HPA-nxV200 modules.The first thing that struck me was the improvment in the bass, very quick and tight.The treble was smooth and detailed, and the resolution just outstanding!I'm very happy with the results.RegardsMark G.
